3900T

Here’s a new crusher being delivered by the Acadia Dock and Terminal System’s heavy tank engine to an earthmoving contractor. Before large cranes like this were available truckloads of wood cribbing and many men would have blocked the flatcar and constructed a ramp down to the lowbed trailer.
The 3900T Manitowoc truck crane was introduced in 1963 and is capable of lifting this 50 ton load at a 30’ radius. More info on the availability of this as a kit can be gained by sending me an email or making a phone call.

Here’s a shot of the new 3900T Manitowoc truck crane lifting the front end of an old gas electric car for maintenance on the power truck. The 3900T first appeared in 1963 and was the biggest of its type at the time. I recently built this and rigged it with a 60 ton block and an eight part line. It is show here working with a 60 foot basic boom at about a 28 foot radius. In this position it can safely lift 50 tons with the spreader bar although lifting the heavy end of the car is should be within 40 tons.
More pictures will posted soon making other heavy picks.

Here’s some shots of the work in progress on the Manitowoc 3900 T truck crane. I have admired this machine since it first came out in 1963, fine Manitowoc engineering and design and the first six axle carrier although Hendrickson was building one for American Hoist at the same time they were building Manitowoc’s.
